ILLINOIS DOL'EY FOR SEPABATING FORDSON TEACTORS.

Application filed October 15, 1920.

T 0 all whom it may concern:

Be it known that 1, Cinemas l3. Kosrnn, citizen of the United States, residing at Chicago in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Doley for Separating Fordson Tractors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention has relation to certain new and useful improvements in a doley or a jack for separating Fordson tractors and hasfor its primary object the provision of :1 raising and supporting device for the sections of the tractor so as to permit of separation of the sections while resting on the doley or jack.

The invention has for another object the provision of a doley or jack for separating Fordson tractors and which will be especially adapted for use in connection with the Fordson type of tractor, one of the raising and supporting members of the device being securely mounted upon the track rails while the other raising and supporting member of the device is movable longitudinally u on said track rails, whereby this second mem' er may be properly positioned beneath the forward section of the tractor,

The invention has for a further object the provision of a doley or separator for tractors. in which the rear axle and transmission housing supporting member may be stationary while the member for raising and supporting the motor part of the tractor may be moved to any position desired upon the track rails.

The invention has for astill further object the provision of a doley or jack of the character stated which will be of comparatively simple construction and operation and which will be highly efficient in use so that the front and rear portions of the tractor may be readily raised and separated and supported when in separated condition or when removing or replacing the wheels upon the axles of the tractor.

-The invention has for still another object theprovision of a doley or ack of the character stated in which the forward jack structure may be readily adjusted upon the track with respect to the stationary or immovable jack structure and each iack structure adjusted vertically independently of the other for raising separately the sections of the tractor.

With the foregoing and other objects in view, as will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of cooperating elements hereinafter more specifically set forth claimed and shown in the accompanying drawings forming a part of the present application and iii-which:

Figure 1 is an elevation of the complete device in use.

Figure 2 is a transverse section on the plane of line 22 of Figure 1.

Figure 3 is a transverse section on the plane of line 33 of Figure 1.

Figure 4 is a transverse section on the plane of line 4-4 of Figure 1.

Referring more in detail to the drawings in which similar reference characters desig nate corresponding parts throughout the several views, 1 indicates the rails ofthe track which are connected by suitable transverse connecting members 2 at the forward end of the track.

The lower or base member 8 of the rear stationary or immovable track structure is secured to the rails 1 by suitable securing bolts 4- or the like passed through the lower portion of the depending supporting legs formed at the corners of the base member This base member 8 has an enlarged or thick ened central portion provided with an interiorly threaded opening forming-a central. socket 6 for the adjusting screw 7 to extend through, the screw 7 having its upper-end secured within a seat 8 formed centrally in the lower face of the upper supporting plate 9 for the rear axle and transmission housing section of the tractor, as indicated at 10 in thedrawings. See Figure 1. A hand wheel 11 is mounted on the screw 7 for raising and lowering the supporting plate 9. Thisplate 9 is provided at its front and rear edges with supports 12 one of which has a concave upper face 18 as will be readily understood by referring to the drawings so that the rear axle and transmission housing section of the tractor maybe properly supported upon the v plate 9. The corner guide posts 1 1 are carried by the supporting plate 9 depending from the corners of the latter, said corner posts 1% extending through suitable guide openings formed vertically inthe baseplate 3.

In order to raise and support the forward portion 16 of the tractor, have provided a movable jack structure which includes a base plate 17 having depending side bracket'members 18 at the corners thereof and through which the shafts 19 are'entended to support the wheels 20 adapted to ride on the rails 1 so that the forward jack structure may be adjusted. upon the track with respect to the stationary or. immovable jack structure for the rear axle and transmission housing'ser-A tion of thetractor, as previously described. The base plate 17 of the forward jack structure has a central. socket 21 formed therein and through which the adjusting screw 22 extends, sa1d ad usting screw bemg one of said flanges 25 having a concaved upper face 26 to conform to the body or base of the motor section ofthe tractor, as shown in Figure 3 of the drawings. The guide posts 27 are also provided for the forward j jack structure and depend from the corners of the supporting plate 23 thereof, said guide posts 27 projecting through sockets or guide openmgs 28 formed in the corner portions of the base plate 17, as also shown in the drawings. The supporting plate 28 will thereby be guided properly in its vertical movement and assist in supporting the tractor.

By referring to Figure 4t of the drawings,

it will be seen that the supporting brackets 18 are bifurcated between which the sup-- porting wheels 20 are positioned. The structure serves to securely support the axles 19 for the wheels 20. v It will be noted by referrlng to Figure 4; of the drawings that the wheels 20 preferably have peripheral, channels which are of substantially V-shape construction in cross section, as shown. at

29, so as toconform to the rails 1 which are.

preferably'of inverted ill-shape construction, as also shown clearly in Figure ,4: of the drawings. i

By referring to thefo'regoing paragraph taken in connection with the accompanying drawings,- it will be seen that the forward jack structure may be adjusted upon the track rails 1 independently of the rear jack structureand each of the forward and rear jack structures may be manipulated independently of each other to raise and prop erly support the sections of the tractor resting thereon, while the portions of the tractor are" separated .during the operation. of

removing or replacing the wheels or repairing any other portion of the tractor. It will be evident that suitable means may be employed to prevent movement of the forward jack structure. upon the track and the portion of the tractor resting thereon, when desired.

While the preferred embodiment ofthe invention has been shown'and described, it will be understood that minor changes in the details of. construction and arrangement of parts may be resorted to within the'scop'e" of what is claimed without departing from the spirit of the invention.

What is claimed is: I 1. A. jack of the character described comprising a supporting track, an immovable jack structure for supporting a portion "are tractor above said track, and a movable "jack structure mounted on said track and adapted to operate independently of the first-mentioned jack structure to support a portion of the tractor above said "track.

2. A jack of the character described comprising an immovable jack structure, a

track, said immovable jack structer teing mounted on said track and including a sup porting base anda supporting plate, means.

for adjusting said supporting plate with respect to said supporting base, and a for-' ward jack structure adjustable along the said track and adapted to be manipulated independently of the rear ack structure,

3. A jack of the character described coin prising a track, a stationary jack structure secured upon said track, a movable'jack structure mounted'on said track and including a supportingbase, supporting plates positioned above and adjustable with respect to said supporting base, said supporting plate carrying supporting members upon its'upper face, and guide means for. said supporting plate. I

4.; A jackofthe character described com prising a pair-of jack members including supporting bases and supporting plates, means for adjusting said supporting plates vertically with respect. to'said respective supporting bases, one of said jack members being movable upon a track andv adjustable with respect'to' the remaining jack member,

and guide means for the supporting plates of said jack members.

5.1%. jack of the character described comprising a track, a base member of a jack structure secureduponone end'of thetrack, asupporting plate'adjustably 'mounted' on said base member, a second jack structure including a supporting base, a supporting plate adjustably mounted upon the supporting base of the second jack structure, bracket members depending from the base of said second jack structure, and supporting wheels mounted in said bracket members and adapted for movement upon the rails of said track to adjust the second jack structure with respect to the first mentioned jack structure.

6. A doley comprising a pair of jack structures of which one jack structure is movable with relation to the other.

7. A doley comprising a base, a pair of jack structures carried by said base of which one of said jack structures is movable on the base with relation to the other.

8. A doley comprising a pair of jack structures, and wheels supporting one jack structure to permit it to be moved with respect to the other.

In testimony whereof I affix my signature 20 in presence of two witnesses.
